The tech industry celebrates busyness as a badge of competence. "Shipping fast", "moving at the speed of the market", and the quiet normalization that you're always already behind. I've been in this industry long enough to notice the pattern. Every few years, someone disappears from LinkedIn for a while. They come back different: quieter, more measured, sometimes having left tech entirely. When you ask what happened, the word is always the same: burnout.
The learning treadmill
What's specific to tech is that the requirement to grow never pauses. It's not enough to be good at what you currently do. By the time you've mastered something, there's a new paradigm that makes your expertise look dated. Or so the story goes. I think the story is mostly true and slightly dishonest at the same time. Yes, the landscape changes fast. But most valuable skills — thinking clearly, asking the right questions, understanding trade-offs — have a much longer half-life than the tools and frameworks that carry them. We confuse the packaging with the content.
Growth that leaves you depleted isn't growth. It's extraction. The industry is very good at consuming people who can't tell the difference.
What sustainable looks like
I don't think the answer is to grow less. I think it's to grow differently: to be more selective about which hills are worth climbing. To accept that you can't know everything, and get comfortable with that without letting it become an excuse for complacency. Sustainable learning in tech looks like maintaining a small number of deep skills rather than a vast surface of shallow ones. Knowing what you're willing to let get outdated. Building recovery into your schedule rather than treating it as a reward for finishing.
It also looks like paying attention to how you feel after a week of intense learning versus a week of stagnation. The goal is to find the rhythm in between: engaged, challenged, but not depleted.
